Answer;
1/3N(g)+H(g)—>1/3NH3(g)
Answer:
His speed was 2 m/s, and his velocity was 0
Explanation:
In physics, speed of an object is defined as the change in position with the change in its time. While velocity may be defined as the change in the position of the body with respect to the time taken.
Speed in a scalar quantity which means it has only magnitude while velocity has both magnitude and direction.
To determine change in velocity both direction as well as magnitude has to be changed.
In the context, Kai was 200 m of the library in the north direction. Now for the round trip to the library and back to his position, Kai took 200 seconds time to cover the distance.
So for the round trip, the speed of Kai would be 2 m/s abut the velocity of Kai is 0 as the displacement of Kai is 0.
Explanation:
Half life = 129s
Initial Concentration = 0.527M
Rate constant = ?
Order of reaction = ?
The half-life equation of a first-order reaction does not include a reactant concentration term. A half-life is independent of concentration and remains constant throughout the duration of the reaction.
Order of reaction = First Order
t1/2 = 0.693 / k; where k = rate constant
129 = 0.693 / k
k = 0.693 / 129 = 0.00537s-1
Hey there!
HC2H3O2(aq) + H2O(l) → H3O⁺(aq) + C2H3O2⁻(aq)
↓ ↓ ↓ ↓
acid base acid base
If we consider the only forward reaction H3O⁺is the conjugate acid of the base H2O
. For reversse reaction CH3COOH is the conjugate acid of the base CH3COO⁻.
Hope this helps!
